SLAT-ADJUSTER.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed July 12,1906. Serial No. 825,885.

To all whom it may concern:

Be it known that I, J OHN 0. SMITH, a citizen of the United States,residing at N orwich, in the county of New London, State of Connecticut,have invented certain new and useful Improvements in Slat-Adjusters andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. a

This invention relates to shutters and more particularly to slatadjusters therefor, and has for its object to provide a slat adjusterwhich will be simple and Cheap, which will be so constructed that itwill be unlikely to become broken or deranged, and which may be operatedto move the slats of the shutter and to hold them at different points oftheir movement.

Other objects and advantages will be apparent from the followingdescription, and it is to be understood that I do not desire to belimited to the exact details of construction shown and described forobvious modifications will occur to a person skilled in the art.

In the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views,Figure 1 is an elevational view, showing a portion of a shutter providedwith the present invention. Fig. 2 is a longitudinal section of theadjuster, taken on line 22 of Fig. 1. Fig. 3 is a bottom plan view ofthe block.

. Referring now to the drawings, there is shown a shutter including sideuprights 5, having horizontal slats 6 pivoted therebetween, and a lowerconnecting member 7. A vertical shift rod 8 is pivoted to the severalslats 6 and has a U-shaped plate 8 engaged therewith at its lower end,the plate lying against the forward and side faces of the shift rod.

A yoke 9 has its arms located at opposite sides of the shift rod, withtheir extremities against the spaced portions of the plate 8, and withits bight beneath the lower end of the shift rod, and fastening devices10 are eninto the shift rod, to pivotally connect the yoke with theshift rod for movement toward and away from the shaft.

The bight of the yoke 9 carries a downwardly extending stem 11 providedwith notches 12 in its forward face, and secured to the connectingmember 7 of the shutter, there is a block 13 which extends forwardlytherefrom in the form of a nose 1.4, and this block has a slot formedlongitudinally in its nose and extending vertically, the slot openingthrough the rearward face of the block and being thus closed at itsrearward end by the connecting member 7. The block may thus be readilyengaged over the stem 1 1, as will be readily understood, and theforward portion of the nose is reduced in thickness vertically to enterthe several notches 12 interchangeably. As shown, the slot of the blockis enlarged laterally within the nose, as shown at 15, to receive ahelical spring 16, the slot itself being indicated at 15, and the springthus bears at one end against the stem 11, and at its other end againstthe member 7, to hold the stem yieldably a ainst movement to disengageits notches rom the forward portion of the nose. At its lower end, thestem 11 is provided with a finger piece 16 which may be pressed to movethe stem against the action of the spring, when the stem may be operatedto shift the slats 6, as will be readily understood.

What is claimed is:

The combination, with a shutter including a frame and horizontal slatspivoted thereto, of a shift rod pivoted vertically to said slats; aU-shaped plate secured to the forward face of the lower end of said rod,said plate having its arms extending across the opposite side faces ofsaid rod; a yoke having its opposite arms pivotally secured to thecorresponding plate arms, the bight portion of said yoke carrying adepending stem provided with notches formed on its forward face; aforwardly projecting block secured to the lower member of the shutterframe and provided with a longitudinal slot through which said yoke endis adapted to pass, said slot having a gaged through the arms and theplate 8 and 1 closed forward end and being enlarged later ally; a springdisposed Within the enlarged slot, topermit the verticaladjustrnent ofsaid portion of said slot and adapted to bear shift-rod. 10 against saidnotched stem to hold the latter In testimony whereof, I a'ffixmysignature, normally in engagement with the closed end in presence oftwo witnesses.
